BOX.

Application filed March 11, 1924. Serial No. 698,520.

To all whom it may concern:

Be it known that I FREDERICK A. Rose, a object of the King of GreatBritain, residing at Memphis, in the county of Shelby and State ofTennessee, have invented certain new and useful Improvements in Boxes,of which the following is a specification.

'lvlysaid invention relates to a collapsible paper box and it is anobject of the same to provide a box which can be shipped 1n collapsed orknock-down position but which whenopened is practically as rigid as anystiff box on the market.

Another object of the invention is to provide a collapsible box with abottom which when once forced into place will hold its position firmlyand which bottom cannot be folded again or is at least so nearlyimpossible to refold as to insure that the box will not collapse byaccident.

Referring to the accompanying drawings which are made a part hereof andon which similar reference characters indicate similar parts,

Figure 1 is a perspective of my improved device,

Figure 2, a vertical section of the same in partly open position,

Figure 3, a section at a corner next to one end of the joint in thebottom of the box with parts broken away.

Figure 4, a perspective of the bottom in operative position with partsbroken away to show the construction more clearly,

Figure 5, afragmentary plan of the bottom, and

Figure 6, a fragmentary perspective at one corner.

In the drawings reference character 10 indicates the outer wall of a boxhaving a bottom consisting of duplicate sections 11 and 12 each formingone-half of the bottom. These sections have downwardly extending flapswhich are rigidly united as indicated at 13 and a strip of material 14is inserted between such downwardly extending flaps said materialterminating short of the ends of the joint as clearly shown in Figures 4and 5. A staple 15 is indicated by Figure 5 as providing means foruniting the flaps 13 and the strip 14 but any other desirable orconventional means may be provided for this purpose. The top edges pf Sde 1? are preferably reinforced by inturned flanges which stiffen andbrace the structure when the box is closed.

At the sides parallel to the joint of the bottom sections the lower endsof sections 11 and 12 are crimped to form flaps 16 which extend beneatha flap 17, the latter flap being continuous about the bottom of the boxor substantially so to provide a strong bottom rim or edge forsupporting the box. The outer crimped edges 16 of the bottom sections 11and 12 are secured to the flap 17 and to the outer wall of the box byrivets or glue or in any other convenient manner. At the remaining sidesof the box the outer crimped edges 16 of the side sections slip behindthe flap 17' when the bottom is forced downward into operative position.

The outer wall of the box preferably consists of two duplicate sectionshaving in.- wardly folded flaps secured together by glue or the like toform guides 18 for the spaced-apart projecting outer ends 19 of theflaps 13 by which the bottom sections are connected to each other, (Fig.5), these flaps being secured together by glue or the like and heldapart at the ends by means of the strip 14 for convenience in positioning the bottom in relation to the guides 18. It will be seen that thespaced outer ends 19 can slide freely down along the guides 18 inopening the box.

Extensions 19 are preferably cut back at 20 (Fig. 4) for convenience insliding the bottom to position since otherwise the cor- 11ers mightcatch against the wall of the box. The guides 18 are cut away at thelevel of the bottom as indicated at 21 in Figure 6 so that the ends ofstrip 14 will slide past and underneath the shoulder thus formed therebylocking the parts together since the end of the strip 14 cannot pass theshoulder in the reverse direction. Preferably this look is so strongthat it is necessary to damage the box before the strip can bedisengaged from the shoulder, this making it a very satisfactory devicein use due to the absence of accidental collapse of parts. It will beobvious to those skilled in the art that various modifications may bemade in my device without departing from the spirit thereof andtherefore I do not limit myself to what is shown in the drawings anddescribed in the specification but only ;as indicated in the appendedclaims.

Having thus fully described my said incorners for guiding the sectionsof the bottom, and means at said corners for locking the bottom inposition when fully opened,

substantially as set forth.

A collapsible box comprising collapsible side members, a folding bottom,flanges projecting inwardly from opposed corners of the box at the endsof certain of said joints for guiding the bottom sections said flangesbeing cut away adjacent their lower ends to provide shoulders adapted toextend over the bottom sections to lock the bottom in place,substantially asset forth.

3. A box comprising collapsible sides, a folding sectional bottom,guides projecting inwardly of the box at opposite corners said guidesengagingbetween sections of the bottom, and a strip of cardboard or thelike separating the sections of the bottom and terminating short ofsaidopposite corners said strip being of substantially equal thicknesswith said guides, substantially as set forth.

A box comprising collapsible sides, a folding sectional bottom,guides projecting inwardly of the box at opposite corners said guidesengaging between sections of the bottom, a strip of cardboard or thelike separating the sections of the bottom and terminating short of thecorners said strip being of substantially equal thickness with saidguides and said guides having shoulders adjacent their lower endsadapted to engage over the strip when the box is fully opensubstantially as set forth.

In witness whereof, 'I have hereunto set my hand and seal at Memphis,Tennessee, this 1st day of March, A. D. nineteen hundred andtwenty-four.
